Recent Results of the Relativistic Green's Function Model in Quasielastic Neutrino and Antineutrino-Nucleus Scattering

Abstract

The analysis of quasielastic neutrino and antineutrino-nucleus scattering cross sections requires relativistic theoretical descriptions also accounting for the role of final-state interactions (FSI). In the relativistic Green's function (RGF) model FSI are described by a complex optical potential where the imaginary part recovers the contribution of final-state channels that are not included in other models based on the impulse approximation. The RGF results are compared with the data recently published by the MiniBooNE and MINER$\nu$A Collaborations. The model is in general able to give a good description of the data.
